Product description
Intended use
The UMG96S has been designed for a fixed in-
stallation in panels, measuring voltage, current,
power etc. in low voltage switchgear. The meas-
urement is laid out for three phase systems with
neutral conductor (TN and TT networks).
The UMG96S gets its operating voltage from the
measuring voltage and can be delivered for
operating voltage of 150V and 300V. The 300V
standard version, measurement and operation
voltage (50Hz/60Hz) up to 300VAC against
ground and 520VAC phase to phase can be
connected directly. The 150V special version,
measurement and operating voltage (50Hz/
60Hz) up to 150VAC against ground and
240VAC phase to phase can be connected di-
rectly.
The measurement and operational voltage must
be connected to the UMG96S via a separation
(circuit breaker or power switch) and a fuse (2-
10A) within the installation. The separation
(circuit breaker or power switch) must be near
to the instrument and easy to reach.
The connection of the measurement and oper-
ating voltage is carried out on the backside of
the UMG96S via touch proof spring terminal. To
the current inputs, either .../5A or .../1A trans-
formers can be connected.
Attention!
Measurement in systems with pulse load
is not possible, because no continuous
scanning of the measuring signals is car-
ried out.
m
Attention!
The inputs, outputs and serial interfaces
must be shielded.
m
Attention!
The connection of the neutral conductor
N is absolutely neccessary.
